Xavier, did you ever give Mt Millais pollen to Yang-Ji in 2016 or maybe earlier? I have a roth in bud with the cross code YJ1553 with a 2016 date on it. I think the cross is 'Tiger' x ' Mt Millais'
I got it through HiLo Orchid Farm.
Based on your post last year Xavier I picked up the last 3 plants he had listed on his website of this cross. He could have more but not listed on his site
One of 3 I picked up from Ten Shin. I took a chance on a F2 cross of PEOY. I also picked up aF2 Lady Isobel which hasn't bloomed yet.
I think this plant has great potential with maturity.
